@darryl c Microsoft Edge should automatically update the TLS certificates for Azure, and users typically don't need to do anything manually. These updates are usually rolled out gradually, so not all users may see the new certificates immediately. However, the process should be completed before the current certificates expire on June 27, 2024.
If you are experiencing issues or seeing no updates a few days before that date, it's a good idea to ensure that your browser is up to date and check for any relevant updates from Microsoft. Feel free to reach out on this post as well.
